# Complex.Asin(Complex) Metoda

## Definicja

Zwraca kąt, który jest sinusem łuku określonego numeru zespolonego.Returns the angle that is the arc sine of the specified complex number.

``````public:
static System::Numerics::Complex Asin(System::Numerics::Complex value);``````
``public static System.Numerics.Complex Asin (System.Numerics.Complex value);``
``static member Asin : System.Numerics.Complex -> System.Numerics.Complex``
``Public Shared Function Asin (value As Complex) As Complex``

#### Parametry

value
Complex

Liczba złożona.A complex number.

#### Zwraca

Kąt, który jest sinusem `value`łuku.The angle which is the arc sine of `value`.

Poniższy przykład ilustruje Asin metodę.The following example illustrates the Asin method. Pokazuje, że przekazywanie wartości zwracanej przez Asin metodę Sin do metody zwraca oryginalną Complex wartość.It shows that passing the value returned by the Asin method to the Sin method returns the original Complex value.

``````using System;
using System.Numerics;

public class Example
{
public static void Main()
{
Complex[] values = { new Complex(2.3, 1.4),
new Complex(-2.3, 1.4),
new Complex(-2.3, -1.4),
new Complex(2.3, -1.4) };
foreach (Complex value in values)
Console.WriteLine("Sin(Asin({0})) = {1}",
value, Complex.Sin(Complex.Asin(value)));
}
}
// The example displays the following output:
//       Sin(Asin((2.3, 1.4))) = (2.3, 1.4)
//       Sin(Asin((-2.3, 1.4))) = (-2.3, 1.4)
//       Sin(Asin((-2.3, -1.4))) = (-2.3, -1.4)
//       Sin(Asin((2.3, -1.4))) = (2.3, -1.4)

## Uwagi

Metoda dla liczb zespolonych odpowiada Math.Asin metodzie liczb rzeczywistych. AsinThe Asin method for complex numbers corresponds to the Math.Asin method for real numbers.

Asin Metoda używa następującej formuły:The Asin method uses the following formula:

-ImaginaryOne * Log(ImaginaryOne * wartość + Sqrt(One -Value * wartość))-ImaginaryOne * Log(ImaginaryOne * value + Sqrt(One - value * value))
